Untitled Theme Issue: Title Text Wrapping

I switched over to the "Untitled" theme and love it, but on the index page, some of the titles of my posts are displaying improperly. Rather than bumping the text down to the next line if it's too long to properly display, it simply cuts the word off and continues it on the next line. For example, "Hannibal Renewed" should display as

Hannibal
Renewed!

but instead shows up as

Hannibal Renewe
d!

What's strange is that this doesn't affect all of the longer titles, as some of them that are long enough to be multi-line display just fine (and on more lines than the problematic ones).
